I have found a workaround for this issue.
Just goto Pokemon\GameModes\German translation 0.8\Scripts\Attacks.lua
Change the line 15:
RegisterAttack(15,"Zerschneider","The target is cut with a scythe or a claw. It can also be used to cut down thin trees.","Attacks\\Normal\\Cut")
to
RegisterAttack(15,"Cut","The target is cut with a scythe or a claw. It can also be used to cut down thin trees.","Attacks\\Normal\\Cut")
Unfortunately, the P3D engine do not support HM translation hence it fails to work. ( Due to the fact that the moves are hard coded, there is a side effect on this )
Since this is not within the scope for
@Test3r to fix it ( He just started translating and no additional scripts added)... In fact he might not even know this by default, just do the above and continue your game.
You will still encounter more problems later for other HM which I lazy search the entire file...
